What Do these Warning Lights Mean? | Ruston, LA

If you have ever stressed out over a new warning light, we are here to help. Here are some of the most common indicators and what those warning lights mean.

Check Engine

Nearly everyone recognizes the dreaded Check Engine light. Depending on the light, it could be something as simple as a loose or missing gas cap to something much more catastrophic. If it’s a steady glow, then it’s not as serious and you can schedule a visit to the mechanic in the near future. If it’s flashing, it’s serious and you should stop right there and call a tow truck.

Coolant Temperature

When this light turns on, it means you engine is getting too hot. It could indicate low coolant, a coolant leak, problem with the radiator, or a broken fan.


This battery symbol means the voltage level has fallen below normal operating levels. Check your battery to make sure all cables are properly connected.

Oil Pressure

When you see a picture of an oil can, your vehicle has detected a loss in oil pressure. Don’t wait: you need to check your oil level as soon as possible. Driving your car with little to no oil can result in major engine damage.

Tire Pressure

If one or more of your tires is running low on air pressure, this light will turn on. When you see it, refill your tires with air as soon as you can.
